Question

我通过以下方式安装django：

git clone git：//github.com/django/django.git

pip install -e django /

我使用Ubuntu 16.04。

但是会出现一些错误：

Obtaining file:///home/leo/django
    Complete output from command python setup.py egg_info:
    Traceback (most recent call last):
      File "<string>", line 1, in <module>
      File "/home/leo/django/setup.py", line 32, in <module>
        version = __import__('django').get_version()
      File "django/__init__.py", line 1, in <module>
        from django.utils.version import get_version
      File "django/utils/version.py", line 60, in <module>
        @functools.lru_cache()
    AttributeError: 'module' object has no attribute 'lru_cache'

    ----------------------------------------
Command "python setup.py egg_info" failed with error code 1 in /home/leo/django/

如何解决这个问题？谢谢。

Answer 1

最后一个Django版本不支持python 2.7。

如果你真的想使用python 2.7并且还使用Django，你应该安装以前的Django版本。

最新支持的是：1.11

因此，只需运行：

pip install django==1.11

Answer 2

这是因为django版本需要python3解释器。所以尝试使用pip3

运行相同的命令

安装pip3 sudo apt-get -y install python3-pip

然后运行

pip3 install -e django/

Answer 3

您可以使用git安装Python 2的Django版本 - 您只需要先检查正确的发布标记。尝试像

这样的东西

git clone git://github.com/django/django.git
cd django
git checkout 1.11.0
cd ..
pip install -e django/

也就是说，正如其他解决方案所暗示的那样，你最好直接使用pip。
